Answer:
Step-by-step explanation:
This question is asking you "what angle gives you a cos of -square root 3/2"? The cosine by definition is the side adjacent to the angle over the hypotenuse. So set up the right triangle. We do not know which quadrant we are in since we are not told that, but if the cos is negative, then we are in either QII or QIII. In QII this is a 150 degree angle, and in QIII this is a 210 degree angle.
Construction.
When construction workers need measurements that are fractions they need to be able to multiply/add/subtract/divide all of those different fractions and mixed numbers.
I hope I was able to help. Best of luck.
Answer:
prima
Step-by-step explanation:
The velocity or speed of the kayaker going north at a speed of 3 m/s and that of the current going east at a speed of 2 m/s create a resultant speed of √13 m/s. The new distance that has to be traveled by the kayaker in order to move 100 m north is calculated through the equation,
3 / √13 = 100 / x
The value of x is 120 m. The total time it will take for the kayaker to reach the destination is,
t = 120 / √13 = 33.33 s
F(x)=x2,
g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric aroung y axis. When x=1/3 or -1/3, then y=1.
So, try to draw the graph.
